Dialogic I-Gate 4000 Session Bandwidth Optimizer Core X

Transcription

1 The () is a standalone equipment solution designed to deliver a large reduction in the bandwidth requirements and the traffic load (packets per second) for VoIP, Nb, or IuCS traffic, allowing for significant CAPEX and OPEX savings. It is a versatile solution, which can be deployed to optimize traffic carried in applications such as: Between VoIP media gateways (VoIP traffic optimization) Between 3G mobile media gateways (Nb traffic optimization) Between a 3G mobile media gateway and a Radio Network Controller (IuCS traffic optimization) Between a Session Border Controller and VoIP media gateways (VoIP traffic optimization) Between a Session Border Controller and 3G mobile media gateways (Nb traffic optimization) Between Session Border Controllers (VoIP or Nb traffic optimization) The can leverage sophisticated in-house bandwidth and IP packet rate optimization technologies, while preserving the quality and reliability of the original VoIP, Nb and IuCS traffic. By combining high-quality VoIP, Nb and IuCS traffic optimization techniques, the can serve as a powerful CAPEX and OPEX savings option for operators that have deployed 3G mobile networks as well as for operators and service providers using VoIP interconnecting networks. Features Leverages sophisticated bandwidth and IP packet rate optimization technologies from Dialogic, while preserving the quality and reliability of the original VoIP, Nb and IuCS traffic Automatically detects and processes VoIP, Nb and IuCS traffic streams without requiring control or external equipment for its operation Networking transparency Benefits Can enable substantial CAPEX and OPEX savings for VoIP media gateway, 3G mobile media gateway and Session Border Controller traffic carrying applications Enables cost-effective transport of VoIP, Nb and IuCS traffic in 3G mobile networks, in VoIP next-generation switching networks and in VoIP or Nb interconnecting networks Allows seamless insertion of an terminal into deployed links and interconnection to operating networks without having to modify existing equipment or network topology % (six 9s) availability Provides high reliability at both the terminal and network level Supports a wide range of transmission infrastructure Can be used in terrestrial, radiolink, and satellite installations

2 High Bandwidth Savings The can significantly reduce the bandwidth required for 3G Nb and IuCS traffic, as well as VoIP traffic from service provider or enterprise media gateways, while preserving the original voice quality. The automatically detects and processes the Nb, IuCS or VoIP traffic streams without interworking with a control or signaling element. Usually, deployed VoIP and 3G mobile media gateways use bandwidth optimization techniques such as encoding and silence suppression; however, the overall optimization level of these systems can be relatively low. In contrast, the uses distinctive bandwidth optimization algorithms and techniques to optimize the already-compressed VoIP, Nb or IuCS traffic without degrading the original traffic quality. See Figure 1, Chart A example and accompanying description. IP Network Optimization The can significantly reduce the original VoIP, Nb or IuCS packet rate (packets per second) load while providing full application and services transparency. Packet rate reduction can help release core IP network router resources, which, in addition to contributing to CAPEX and OPEX savings, can help enhance overall Quality of Service. See Figure 1, Chart B example and accompanying description.

Performance Figure 1 shows an example that compares the bandwidth requirements (Chart A) and the packet rate (Chart B) of VoIP traffic before and after an solution has been deployed. In Chart A, the green column depicts the bandwidth requirements before deploying an I-Gate 4000 SBO-CX solution and the blue column depicts the bandwidth requirements after deploying an solution. Similarly, In Chart B, the green column depicts the packet rate before deploying an solution and the blue column depicts the packet rate after deploying the an solution. Applications Between s The allows for cost-effective optimization of the Nb traffic streams transported between the 3G mobile media gateways (Nb interface) while also being able to maintain the quality and reliability of the transported calls and to significantly reduce IP router processing resources and operations. See Figure 2 for an example configuration. 2

3 Optimized IP Network Figure 2. Network Nb VoIP Sessions Optimization Similar benefits also are available when deploying an to optimize the IuCS traffic streams transported between Radio Network Controllers (RNCs) and 3G mobile media gateways (IuCS interface). See Figure 3 for an example configuration. RNC Optimized IP Network Figure 3. Network IuCS VoIP Sessions Optimization Between VoIP s Operators are deploying next-generation switching networks that include VoIP media gateways and softswitches. A number of VoIP media gateways use bandwidth and IP load optimization techniques that often provide only a small reduction in bandwidth consumption and packetsper-second rate. RNC Optimized IP Network Figure 4. Next Generation Switching Network Optimization Able to fit transparently between media gateways, the can allow for substantial CAPEX and OPEX savings by further reducing the bandwidth required and the packet rate of the VoIP traffic generated by the VoIP media gateways, while maintaining the quality and reliability of the transported calls. See Figure 4 for an example configuration. 3

4 Satellite Applications For telecom operators and service providers carrying VoIP, Nb or IuCS traffic over costly or bandwidth-bounded satellite links, bandwidth optimization systems that use provide an unparalleled solution that is capable of delivering substantial savings on bandwidth resources, network equipment and operations, while also providing high-quality services as well as efficient utilization of the existing transmission infrastructure and satellite modem routers. See Figure 5 for an example configuration.

VoIP or Optimization in a Satellite Network Call Centers and Enterprise VoIP The rapid development of call centers and broadband access for enterprise customers and the growing demand for IP-based voice and data services have combined to pose a challenge to operators aiming to maximize the utilization of their transmission network infrastructure. The optimizes the VoIP sessions between multiple VoIP media gateways or IP PBXs while preserving the original voice quality. It also is capable of providing a considerable bandwidth savings and significantly reducing the VoIP packet rate (packets per second), while maintaining the quality of the voice traffic.
